First of all the bad reviews these filters have have nothing to do with filters. Your problem is that your filter system is complex, no filters. I bought them under my wife's account but have been checking them under my account since I bought and installed them. Water filtration system is excellent. We wanted to replace the old one with the new one, it was a little tricky figuring out how to remove the original cartridge from the filtration system, but once I figured that out it was really easy to install. I'll be installing a new one soon so I'll add pictures to show the difference. I will definitely buy these filters again. Such a great product once you figure out your filtration system and how to change filters.
